Item Desenvolvimento de um framework para o alcance da mentalidade de riscos como requisito da ABNT NBR ISO 9001:2015(Universidade Federal de Goiás, 2024-01-24) Cabral, Gabriella Silva; Fonseca, Marcelo Nunes; http://lattes.cnpq.br/9285142449945121; Fonseca, Marcelo Nunes; Dantas, Maria José Pereira; Rabelo, Diogo de SouzaThe increasing pursuit of ISO 9001:2015 certification by organizations, through the implementation of a Quality Management System (QMS), reflects the aim of securing a competitive advantage in the market by maintaining high standards of quality in processes and projects. However, obtaining certification requires organizations to embrace risk-based thinking, which is linked to their cultural aspects. Risk-based thinking during project and operational execution should naturally and intrinsically be part of organizational routines. Nevertheless, there are challenges to this implementation, such as a lack of knowledge about risk management and the difficulty in making the routine of risk-based thinking tangible or evident for certification audits. Therefore, this study aims to present the development and application of a risk management framework to introduce risk-based thinking in organizations, following an agile and assertive approach. The action research method was implemented, following a flowchart that encompasses planning, data collection, analysis, implementation of actions, and evaluation of results. The framework was developed based on an understanding of regulatory requirements and best practices in risk management and governance. It was applied in two real projects: "Project ABC" involving the importation and launch of a medical device, and "Project CQ Software", dedicated to the implementation of software within 90 business days. The implementation of the framework allowed the organization to optimize processes for identifying, analyzing, and responding to imminent risks. In "Project ABC", the model's application enabled the company to revise the pricing method for the equipment, creating opportunities for project gains. In "Project CQ Software", the quantitative analysis of the schedule demonstrated the feasibility of applying the PERT method for project schedule forecasting. In summary, the model proved to be applicable, becoming a driver for improvements in the risk management processes of the organization under study.Item Avaliação da satisfação do usuário de telefonia móvel da região Centro-Oeste por meio da modelagem de equações estruturais(Universidade Federal de Goiás, 2023-10-24) Oliveira, Juliane de Sousa; Santos Neto, Agenor Sousa; http://lattes.cnpq.br/6615964725213306; Soares, Júlio Cesar Valandro; http://lattes.cnpq.br/9557844115914458; Soares, Júlio Cesar Valandro; Santos Neto, Agenor Sousa; Almeida, Tiago dos Santos; Duarte, Márcio AntônioIn order to maintain competitiveness and profitability, telephone companies seek indices that assess customer satisfaction. Understanding the level of consumer satisfaction regarding the use of mobile phone services is essential, since this type of communication provides ease and is present in the majority of the population. This work aims to present the main factors that impact on mobile telephony user satisfaction in the Midwest Region. This research was developed with the aid of the questionnaire carried out by Anatel.

Structural Equation Modeling was used to assess consumer satisfaction in the Federal District, State of Goiás, State of Mato Grosso and State of Mato Grosso do Sul. Each location got different results. For the Federal District, of the six hypotheses analyzed, two were rejected. For the State of Goiás, of the six hypotheses analyzed, two were also rejected. For the State of Mato Grosso of the six hypotheses tested, only one hypothesis was rejected. The State that obtained the highest number of rejections of the hypotheses was the State of Mato Grosso do Sul, of the six hypotheses analyzed, three were rejected. Of all the hypotheses analyzed, the customer expectation factor proved to be significant and positive in the perceived quality and value perceived by the consumer.Item Proposta de relato integrado de valor para um curso de graduação em engenharia em uma universidade pública(Universidade Federal de Goiás, 2023-12-12) Santos, Diorgenes dos; Sousa, George Wagner Leão e; http://lattes.cnpq.br/1372987452901677; Severino, Maico Roris; http://lattes.cnpq.br/2546008836929749; Severino, Maico Roris; Soares, Júlio César Valandro; Zaro, Elise Soerger; Sousa, George Wagner Leão eThis research addresses the challenge that governance and management represent for public organizations, specifically an undergraduate course at a public university, and the need for tools that help in the task of analyzing, relating and interpreting information, minimizing risks and presenting important findings on how enterprises generate value for their stakeholders. The research proposes the structuring of an Integrated Value Report for an undergraduate course at a public university in the state of Goiás. It seeks to build the basis of the model, with a literature review on the CDIO Initiative, Management System with Agile SD as a control architecture approach and Integrated Reporting, seeking to determine the necessary requirements for the implementation of an Integrated Report and considering the possible definition of the Generic Architecture of Integrated Value Reporting for an undergraduate engineering course. The CDIO approach supports the understanding of the system's life cycle, considering interactions, innovation, improvement, user needs and technological constraints. Agile SD aids the understanding of causal relationships that influence past and future performance. Despite the growing importance of integrated reporting for governance and management, there is a lack of studies on integrated value reporting applied to undergraduate courses. This study seeks to fill this gap by proposing an integrated value reporting model for an undergraduate engineering course at a public university in the state of Goiás. This study will use a case study to verify and analyze the feasibility of implementing an Integrated Reporting model applied to an undergraduate course. The study will be carried out in an undergraduate engineering course at a public university in the state of Goiás. Overall, this study has presented solutions, tools and processes that can improve information management practices from an Integrated Value Reporting perspective, making a broad contribution to the maturing of governance and a specific contribution to the structuring of management processes from a systemic perspective, enabling greater precision on the points of investigation for decision-making and guiding the evolution of courses, which in turn can contribute to increasing their maturity.Item Aplicação de sistema fotovoltaico off-grid como backup de energia na zona rural - estudo de caso(Universidade Federal de Goiás, 2023-08-21) Silva, Fernando Carvalho Assunção da; Fonseca, Marcelo Nunes; http://lattes.cnpq.br/9285142449945121; Belchior, Fernando Nunes; http://lattes.cnpq.br/5823317463324641; Belchior, Fernando Nunes; Santos, Ivan Nunes; Rabelo, Diogo de Souza; Fonseca, Marcelo NunesThrough electrical energy, it is possible to operate machinery, generate heat, and transmit information. This energy is generated, transmitted, and distributed until final consumption. However, interruptions in the power supply pose obstacles, especially for producers located in the rural areas of the state of Goiás, within the concession area of the distributor EQUATORIAL-GO. These producers face losses due to spoiled stored food and the death of animals in breeding facilities. With the rise of distributed generation, consumers have been enabled to produce their own energy, thus becoming prosumer. This study conducts a case analysis on a rural property located in the municipality of Cezarina-GO, aiming to investigate the optimal solution for maintaining a consistent energy supply through alternative generation sources. Different scenarios are explored: 1) Grid Electricity + Backup Generator; 2) Grid Electricity + Off-Grid Photovoltaic System; and 3) Grid Electricity + Off-Grid Photovoltaic System + Batteries. Based on the energy demand of the location, equipment is sized for each scenario, and a financial analysis is performed using indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Discounted Payback Period, and Levelized Cost of Energy (LCOE). The analysis considers the main implementation and operational costs for each configuration under study. The results show that the scenario "Grid Electricity + Off-Grid Photovoltaic System + Batteries" exhibits the best feasibility among the analyzed solutions. Despite having an initial investment nine times higher than the more traditional "Grid Electricity + Backup Generator" scenario, it presents a higher negative NPV and a lower LCOE over a 30-year period. Lastly, through a sensitivity analysis, parameters related to the cost of diesel fuel (R$), electricity tariff (R$/kWh), battery bank cost (R$), and the number of power interruptions were modified. Similarly, the "Grid Electricity + Off-Grid Photovoltaic System + Batteries" scenario remained the most viable for the first three analyzed parameters, while the "Grid Electricity + Backup Generator" scenario became more viable only when the number of power interruptions was reduced.Item Detecção de dimensões de bagagens aeroportuárias a partir de dispositivos de baixo custo(Universidade Federal de Goiás, 2023-12-20) Silva, Vitor de Almeida; Bandeira, Michelle Carvalho Galvão da Silva Pinto; http://lattes.cnpq.br/8988187129672006; Roriz Junior, Marcos Paulino; http://lattes.cnpq.br/1356289387726731; Roriz Junior, Marcos Paulino; Rabelo, Diogo de Souza; Guterres, Marcelo XavierRecent studies indicate a significant increase in passenger boarding times, ranging from 22 to 40 minutes between 1990 and 2009. One contributing factor to this delay is the check-in process, primarily stemming from baggage dimension verification. Incorrect dimensions not only impact luggage storage but also result in additional costs for the customer. In such cases, passengers may be required to pay extra fees and return to the check-in line for corrections. To address this issue, companies are investing in self-bag drop systems, where passengers take responsibility for measuring their baggage. However, challenges arise due to the varied shapes of luggage and the complexities of handling multiple checked items. This study reveals that certain devices, particularly those utilizing LASER technology, can automatically obtain baggage dimensions. Despite their effectiveness, these devices often come with a significant price, and may require adjustments to the environment for installation. Consequently, this research aims to explore the technical feasibility of employing low-cost devices to measure airport luggage dimensions. Among the low-cost techniques, the use of the Microsoft Kinect depth sensor stands out, capable of obtaining a point cloud of the object under analysis. Based on this sensor, an algorithm was developed to capture, assemble and analyse the point cloud generated, thus obtaining the size of the luggage. To validate the approach, a prototype was built that contains a mat and a structure to fix the sensor, allowing the configuration of speed and data capture parameters, such as sampling step and capture region. The conducted tests indicate that the Microsoft Kinect V2 depth sensor can accurately capture depth, width, and height data. These results indicate the potential of this low-cost alternative in streamlining airline boarding operations.Item Caracterização tribológica das lâminas de corte de trituradores utilizados no processo de tratamento de resíduos sólido(Universidade Federal de Goiás, 2023-12-18) Souza, Willian Martins; Gonçalves Junior, José Lúcio; http://lattes.cnpq.br/2092647779902026; Bertholdi, Jonas; http://lattes.cnpq.br/0445297015533619; Bertholdi, Jonas; Troysi, Fernanda Christina Teotonio Dias; Ferreira Filho, DemóstenesIn Brazil, changes in production processes are observed due to environmental and social factors, which have as their biggest consequence the increase in the generation of solid waste. Because of these changes, it is essential to improve the efficiency of solid waste treatment processes, Thus, this work seeks to compare in laboratory tests the wear resistance of the cutting blades used in a solid waste crusher in the city of Aparecida de Goiânia, after application of different materials that can be used in the manufacture of the component, since the main problem presented was the loss in productivity in the treatment of waste due to wear of components of the crusher. After collecting a sample of cutting blade was identified through the study of Scanning Electron Microscopy (SEM) with Secondary Electrons (SE) and Backscattered Electrons (ERE), and also with Energy Dispersive Spectroscopy (EDS) that the type of wear preponderant in the tribological pair is the abrasive. From this premise, the laboratory experiment chosen was the rubber wheel wear test, because it is the method that best fits the system wear mechanisms, the same validated according to ASTM G-65. For the rubber wheel wear test were performed using samples of SAE 1060 steel and SAE 410 stainless steel heat treated. The studies demonstrated that it is not feasible to change the material used in the manufacture of the component, since the wear rates of the SAE 410D stainless steel samples were 55% higher than that of the samples that reproduce the condition of the cutting blade. This analysis is not limited only to one field, and can be extended to other sectors, using tribology as a reference, seeking to contribute to the academic production of production engineering, improving solid waste treatment operations.
